Adopt the hydraulic control diaphragm type multifunctional water pump control valve of technique scheme, cancelled the 3-4 root guiding rib on the valve plate seat, do not had guiding rib, can not produce flow resistance and turbulent flow, reduced the valve resistance coefficient, and be difficult for taking place foreign material or cotton fabric suspension and wrapping phenomena, be particularly suitable for sewage treatment industry, and can automatically realize slow the opening of elder generation of controlled speed according to the requirement of Centrifugal water pump light start, the process of standard-sized sheet can be avoided producing and drive the valve water hammer again.Equally; when valve closing; also can realize automatically closing soon earlier according to the flow condition of medium; such two-stage of Slow Close is closed closed procedure again; avoid and eliminate the generation of pump-stopping water hammer, can protect the safety of water pump, motor, pipeline well, be a kind of automatic control and energy-conservation aspect General than like product product of the future more; it can realize automatic control fully under the operating conditions of certain pressure medium.
Compared with prior art, advantage of the present utility model just is:
1, the design of the runner of expanded letter increases area of passage, and the medium turbulent flow is few, and drag losses is little, and energy-saving effect is obvious.
2, no guiding rib design further reduces drag losses, is not prone to the medium foreign material and hangs and wrapping phenomena, and valve medium passing ability strengthens, and keeps the sealability of valve to reduce the valve drag losses.
3, novel structure, compactness, the main valve structure length is shorter than similar valve, and floor space is few.
4, Slow Close valve plate and diaphragm pressing plate form integral body, can realize speed close+the Slow Close two-stage closes, it is effective, safe in utilization relieved to eliminate water hammer.
5, the valve plate upstream face has the water conservancy diversion conical surface, is difficult for producing turbulent flow, reduces flow resistance.
6, valve rod adopts the straight-bar form, and good manufacturability is easy to process, is convenient to dismounting and on-line maintenance.
7, slowly open, the Slow Close time can control and regulate easily.
8, need not other external control power and device.As long as medium has certain pressure just can guarantee the automatically working of valve.
In sum, the utility model is that a kind of safe and reliable, advanced novelty, assembling are easy to maintenance, the multi-functional pump-controlling valve of hydraulic control diaphragm type that flow resistance is less.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, diaphragm seat 2 is housed on valve body 1, diaphragm seat 2 adopts the bolt mode to be connected with valve gap 3, in diaphragm seat 2, be provided with diaphragm 7, in valve body 1, adopt the bolt mode to be connected with valve plate seat 5, on valve body 1, be provided with lining 11, valve rod 10 passes lining 11, its upper end is fixed on the valve gap 3, the bottom that is fixed on valve body 1 is extended in the lower end, valve plate 4 flip sleeves are connected on the valve rod 10 corresponding with valve plate seat 5, valve plate 4 is provided with discharge orifice 14, Slow Close valve plate 6 flip sleeves are connected on the valve rod 10 and pass lining 11 on it and are fixedly connected on the diaphragm 7 by diaphragm top board 8 and diaphragm press table 9, and can move up and down with diaphragm top board 8 and diaphragm press table 9 along lining 11, Slow Close valve plate 6 is corresponding with discharge orifice 14, valve plate 4 seal form bottoms are soft seal, top is hard sealing, valve plate 4 is hard sealing with the seal form of Slow Close valve plate 6, first pilot line, 13 1 ends connect the feed-water end of valve body 1, the cavity of resorption of the other end junctional membrane bar 2, second pilot line, 12 1 ends connect the waterexit end of valve body 1, the epicoele of the other end junctional membrane bar 2.
Referring to Fig. 1, valve body 1 adopts the design of streamline molded breadth valve body.Guarantee the abundant overcurrent of medium, and can not produce turbulent flow; Do not have guiding rib on the valve plate seat 5, can reduce flow resistance; The water conservancy diversion conical surface design of its upper and lower free-moving pilot hole and minimizing flow resistance is arranged on the valve plate 4, and water conservancy diversion conical surface direct casting has the Olive Shape discharge orifice of circumference uniform distribution; In top middle portion the discharge orifice 14 corresponding with Slow Close valve plate 6 arranged; During valve closing, the hard sealing surface on the hard sealing surface of Slow Close valve plate 6 bottoms and valve plate 4 tops is fitted, and has valve rod 10 to pass in its endoporus, and its top and diaphragm 7, diaphragm top board 8 and diaphragm press table 9 are connected to become integral body, can realize being synchronized with the movement; Valve rod 10 is a polished rod, plays the location of movement parts of valve internal and the leading role in when motion, and its two ends are separately fixed on valve body 1 and the valve gap 3; Diaphragm 7 is by diaphragm top board 8 and 9 clampings of diaphragm press table, and diaphragm 8 is separated the back with the cavity of diaphragm seat 2 and valve gap 3 compositions and formed epicoele and cavity of resorption, and upper and lower cavity is not connected.
